Claims

[Scope of utility model registration request]

a first rotation axis and a second rotation axis arranged on the same axis;
A sun roller connected to a first rotating shaft, a fixed outer ring arranged concentrically with the sun roller, and a fixed outer ring arranged in an annular space between the sun roller and the fixed outer ring to roll into contact with the sun roller and the fixed outer ring. In addition, in a planetary roller type power transmission device including a plurality of planetary rollers, each of which is supported by a carrier that rotates integrally with a second rotating shaft, the rotating outer ring and the rotating outer ring are provided on the outer periphery of the fixed outer ring. A pair of flange-like protrusions that face each other and extend in the circumferential direction of the fixed outer ring so as to pass through positions adjacent to one end and the other end in the axial direction of the contact portion with each planetary roller, and these flange-like protrusions. A tightening member is provided for elastically deforming the fixed outer ring by tightening them in the direction of bringing them closer to each other, and the tightening member is tightened by adjusting the amount of tightening of the member to tighten the parts between the sun roller, the planetary rollers, and the fixed outer ring. A planetary roller type power transmission device, characterized in that it is configured to adjust contact pressure.
